Answer: Finding just the right plants to grow over a drainfield can present a real problem. You don't want to hinder the natural evaporation, and you don't want plants with invasive root systems. Grass is the first choice because it wicks water away, helping it evaporate quickly. But, there are some other choices, as well. Groundcovers and shrubs include Ajuga (carpet bugle), Calluna (heathers), cotoneaster, ground ivy, Arctostaphylos (kinnickinick), Vinca (periwinkle) and Saponaria (soapwort). Wildflower meadow mixes look nice in the right setting, too.
Hope this information helps!
